How does the narrative of Damu Anna in Chapter 25 serve as an example of Sai's protective nature towards his devotees?

The story of Damu Anna in Chapter 25 is presented as a prime example of Sai Baba's protective love and mercy. The chapter introduces his story by stating that once faith is established, Sai wards off all misfortunes and grants the desires of his devotees. Damu Anna's experience validates this claim. He was a wealthy but childless man who, through Sai's blessings, was granted sons. This personal miracle, along with his devoted participation in the Ram Navami festival, shows, as the text says, Sai's readiness to protect His devotees and how the Guru-Mother is an "Ocean of Mercy."
